  • nice 10W warm white emitters

    posted by lasermanathome

    in total 30 Watt of high efficient ledchips.Can be put in serie or parallel so many ways to power them .If you use cooling-compound and SUFFICIENT cooling, they will last very long.If you don't...........
    because of the 12V power and the easy combining you can build your light as you want it to be.I know these leds for a long time, no problem at all!Use PWM for dimming them.stable current controll is a must.
    Best buy, you can make combinations you like best and the dissipation of heat is much easier than 20 Watt and higher ledmodules.
  • Useful LED set

    Very bright, probably around the same as a 30W bulb. There is no lens on the LED so the light is spread in a wide beam.
    The LED obviously requires some soldering, it is very easy to solder as the terminals are thin and easy to heat, I used the 9W led driver board to ensure I don't cook the LED. http://www.dx.com/p/9w-3-led-power-drivers-for-mr16-lamp-light-12v-5-pack-66274
    Its all good.
  • poor documentation, but works ok, and at least comes with a cable

    Works in analog mode.Returns either 0 or 1 in digital mode.
    I would like to see wavelength specific sensors, specifically red, orange, yellow, green and blue, so as to get some rudimentary means of measuring light spectrum.I will probably order a handful of these and install color filters that do not degrade in sunlight.
    worth the $4
